STOP-ACTION FOR ORGANS.

SPECIFICATION forming part of Letters Patent No. 664,858, dated January 1, 1901.

Application filed October 20, 1898. Serial No. 694,067. (No model.)

To all whom, it may concern:

Be it known that I, FREDERICK W. HEDGE- LAND, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, haveinvented anew and useful Improvement in Adjustable Combination Stop- Actions for Organs, of which the following is a specication.

This invention relates to the construction of adjustable combination stop-actions for pipe-organs and is an improvement on previous constructions thereof.

The nature of the improvement is fully set forth below and also illustrated in the accompanying drawings, in which- Figure l is a longitudinal vertical section, and Fig. 2 a plan, of the invention. Figs. 3 and 4t are detail sections of the wipers, showing them in dierent positions. Fig. 5 is a section of the wipers, showing the parts in the same position as Fig. 3, but taken on a different line. Figs. 6 and 7 are sections similar to Figs. 3 and Il, showing still other positions. Fig. 8 is a partial side View of one of the locking-bars.

In the drawings, A and B represent two stop-rods of an organ and may serve as types of the series of rods used therein. They are operable at will by the organist in the usual manner. They are each provided with a stud or arm A', through which they may be controlled by the other devices hereinafter described and forming the subject-matter of my present invention.

Arranged transversely of the series of stoprods is a pair of wipers C and D, each carrying a series of adjustable pins acting on the studs A' of the stop-rods, the pins in wiper C being indicated at E and those in wiper D at F. The pins are inserted in sockets formed in the opposing sides of the wipers, and each is provided with a spring G, tending to force it outward. Each pin is also provided with a collar G', which engages the shoulder G2 of its socket and limits the action of the spring. Each pin, furthermore, is notched or grooved at two points G3 and G4, and these notches or grooves are adapted to receive lockingbars H and J, arranged longitudinally of the wipers, the bar H acting on the pins in wiper C and the bar J on those in wiper D. The

bars are movable at the will of the organist, are normally in their locking positions, and are preferably supported by pivoted arms or U-shaped bearings II J', so that they may be carried into and out of action by an endwise movement imparted through connections H2 and J2 and levers H3 J3. A spring H4 is employed with each locking-bar to keep it normally in action.

The pins in one wiper are, it will be noticed, arranged opposite to those in the other wiper, the opposite pairs thereof acting on the same stop rod, and they have two positionsnamely, an outermost position (shown in the case of one pin E and one pin F in Fig. 2) and an inner or retired position (shown by the other pins in the same gure)-and they may be locked in either of these positions by the locking-bars, inasmuch as one or the other ot' the notches in the pins is always in position to receive the bars. It is also a peculiarity of the pins that when the wipers are closed only one of any pair of pins is in its outer position, both pins never occupying either the out or the in position at such times. The wipers are also movable toward or away from each other at the will of the organist through suitable operating devicessuch, forinstance, as the centrally-pivoted lever K and the connecting-rod K', joining said lever to wiper C, and rod K2, joining the lever to wiper D. One or the other of these rods is preferably extended, so it may serve as a means for operating lever K and so it may be within reach of the organist. Either rod may, however, effect a junction with a button, pull, or treadle operable by him. In either case he applies the power necessary to move the lever in the direction desired and moves the wipers simultaneously either toward or away from each other. At Figs. l, 2, 4, and 7 the wipers are shown as having been separated to the limit of their movement (this bei-ng their normal and non-acting position) and at Figs. 3, 5, and 6 as having been brought together. It is only when they are being brought together that they move the stop-rods. In these movements the wipers are guided by upper and lower guides L and M.

With the consti-notion described the operation is as follows: Supposing the organist ICO desires to set a combination, 11e first moves the wipers together or into their near relative position. In so doing such of the pins as happen to be in their outer positions will reverse their corresponding stop-rods, those of the rods which were out being carried to their in positions and those which were in to their ont positions. Thus, referring to Fig. 2, if the wipers are brought together it will be seen that it must cause the reversal of' the two stop-rods there shown, carrying rod A out and rod B in.- The organist now raises the lock-bars H and J and releases all the pins,and thelatter are immediately forced outward'by their springs so far as the studs A will permit. He then while retaining` the lock-bars out of action pulls out such of the stops as he desires to include in the combination which heis setting,moving them in the direction of the arrow shown upon rod A in Fig. 2, and at the same time he pushes in such stops as are then out, but which he does not wish to include in the combination. In so doing the pins in wiper C belonging to the included stops are carried by the studs A of those stops to their inner positions in the wiper and the pins in wiper D belonging to the same stops are given opportunity bythe outward movement of the stop-rods and studs to move to their outer positions in said wiper. By the pushing in of the out stops not included in the combination the pins in wiper C of such stops are allowed to move to their outer positions and those in wiper D are carried inward. The pins belonging to the stops which were already in at the time of commencing the setting operation and which are not included in the combination will be in the same positions as those of the pushed-in stops above described. The organist now lowers the locking-bars and locks the pins and then separates the wipers and pushesin the stop-rods which at a previous stage he had pulled out. This completes the setting operation and leaves the stop-rods free to be moved without affecting the wiper-pins. The combination may be thrown into action at any time by again bringing the wipers together and through the medium of the out pins in wiper D throwing out the rods of the stops embraced in the combination. As shown at Fig. 2, the stop A and its pins are in the position they will be left by the setting on the supposition that that stop is included in the combination, and it will be seen that the bringing ot the wipers together will move the stop out, so it must go into action with the other stops of the combination. In the same figure stop B is shown as being already out, and its pin Ewill necessarily throw it in when the wipers next close.

In Fig. 3 l have shown the wipers as being together,with the stop-rod shown in the front of the igure in its in or non-acting position, while the stop carrying the rear stud A is in its ont or acting position.

Fig. e sho'ws that the wipers have been opened and thc pins all released preparatory to setting.

In Fig. 5 the wipers are shown as again closed,with the stops in the same position as in Fig. 3, this change forcing the pin F of the foremost stop into its socket. If the lock bars are now lowered, pin F will be locked in this position.

Fig. G shows a stop included in the combination and the wiper-pins belonging to it in the posit-ions occupied by them after setting. 7 shows the same parts 'with the wipers opened preparatory t0 resetting.

It will be understood, of course, that any convenient number of my adjustable combination-actions maybe used, each being wholly independent of the others.

It will ordinarily be the case that of the stopoperating pins one pin ol' every pair will bein its inner position, so that the wipers can close without hindrance; but il at the time of commencing to set a combination both series of pins are out then before moving the wipers together the pins should be released from the lock-bars, so as to leave them free to be moved into their sockets by the studs on the stops.
